HTQFR active power filter was designed for internet data center (IDC). It adopted 19inch standard rack having advantages of small size, light weight, safe and reliable.

HTQFR active power filter was designed and manufactured according to industrial product standards. It can meet the various commercial and industrial applications. This product collects harmonic filtering, reactive power compensation and three-phase imbalance correction in one b body. It is an ideal choice for the power quality control.
